I have checked my receipt and his eBay listings and am unable to determine what chip he installed. I do know that I requested and paid extra to have the upgrade chip put in. It was a small cost compared to the overall charge of him getting in there and fixing the problem.
I was the person who originally had my Early 2011 MacBook Pro 15” repaired at RNRComputer. It’s been working fine since, except that the i7 CPU seems to run hotter than it did before the repair. I wondered if sufficient heat sink compound was applied at reassembly.You should be able to see that in About This Mac.
I paid for the AMD 6770 upgrade. About this Mac shows:
AMD Radeon HD 6770M 1024 MB
Intel HD Graphics 3000 512 MB
And System Report shows:

As I said, I’ve had no problems. Still not Metal 2 capable. Were I to effect the repair today, I’d see about getting a 2012 motherboard with the non-problematic GPU plus USB 3 and Handoff-capable Bluetooth. This machine serves as my desktop machine these days.
Part of my mobile solution was to buy a used Early 2015 8GB MacBook Pro 13”, which i recently upgraded to 1TB with
thanks to other posters on this board.
Besides the space, compared to the Apple 512GB AHCI drive, my read speed increased about 30% to ~1400MB/s from 1100 MB/s and write speed by 300% to ~1400MB/s from 450MB/s (according to Blackmagic’s Disk Speed Test before and after substitution). I highly recommend this solution.
I also purchased a heat sink kit and placed a thermal conductive pad on the chip side of the board, so it contacts the case when the drive is installed. There are no temperature sensors in that area, so I can’t give you a before and after thermal comparison.
